What Does Part G Of The Building Regulations Mean For Me?

The building regulations approved Document G states it is for the ‘sanitation, hot water safety and water efficiency’. These regulations are the minimum standards for the design, alteration, and construction of buildings in the UK. They are designed to ensure that buildings are safe, comply with certain rules, and are water and energy-efficient.

Builds will either pass or fail part G building regulations. The regulations refer to new buildings and some building extensions.

First things first though, if you are looking to start a new project, getting building approval is one of the initial steps before starting to build.

The Simplified Building Energy Model (SBEM), for example, is an approved national calculation used to calculate the energy needed to cool, ventilate, heat, and light non-residential buildings over 12 months.

Standard Assessment Procedures (SAP) should be carried out to ensure that new buildings meet the building regulations and all types of energy and environmental policies.

What Happens If You Work Without Approval?

The authorities must ensure that whatever building work is going on, it complies with the building regulations. If the work does not follow the regulations, you may be asked to remove it, or tweak it.

If you do not follow the regulations, you can be prosecuted. If convicted, you might be expected to pay a penalty fee of up to £5,000.


According to the Approved Document G, sanitary accommodation is simply a space containing a water closet, faucet, bidet, bath, shower, sink, washbasin, or any other externally linked source of water. Sanitary convenience refers to the water closet and urinals.

Hot Water Safety

Hot water safety is a requirement when taking on a build, as hot water is used for numerous things, such as cooking, cleaning, bathing, etc. Energy is a necessity in heating water, and the type of equipment installed in a building for the dispensing of hot water has a significant direct effect on its energy use.

Water Efficiency

The provision of clean, usable water is important in any building. Water should be used wisely. To ensure water is not wasted, water consumption calculations should be carried out. Also, water efficiency calculations should be implemented in a new building to ensure that there is a usable water supply in said building.

It is paramount to know about building regulations, what they consist of, and penalties that might be incurred if we don’t comply with them. This knowledge is essential to ensure that buildings are fit for purpose.
